Viewport bottom origin flip · case 05
Origin conversion flips the top edge without accounting for rectangle height.
Case contract
Convert the top coordinate of an in-bounds top-left-origin rectangle to its bottom-left-origin viewport y using the full rectangle height.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
One recorded failure
